Ingredients

• 2 cups all-purpose flour
• 1.75 cups granulated sugar
• 0.75 cup unsweetened cocoa powder
• 1.5 teaspoons baking powder
• 1.5 teaspoons baking soda
• 1 teaspoon salt
• 2 large eggs
• 1 cup whole milk
• 0.5 cup vegetable oil
• 2 teaspoons pure vanilla extract
• 1 cup boiling water
• 12 pieces Reese's Peanut Butter Cups
• 1 cup unsalted butter
• 0.5 cup creamy peanut butter
• 4 cups powdered sugar
• 0.25 cup heavy cream
• 1 cup mini Reese's candies (or additional chopped Reese's Peanut Butter Cups)
• 0 as needed chocolate syrup (optional, for garnish)

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper.

Step 2

In a large mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.

Step 3

Add the eggs, milk, vegetable oil, and vanilla extract to the bowl. Mix until well combined.

Step 4

Slowly stir in the boiling water. The batter will be thin, but that's normal.

Step 5

Divide the batter evenly between the prepared cake pans.

Step 6

Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center of the cakes comes out clean.

Step 7

Allow the cakes to cool in the pans for 10 minutes, then transfer them to wire racks to cool completely.

Step 8

While the cakes are cooling, make the peanut butter frosting. In a large bowl, beat the butter and peanut butter together until smooth.

Step 9

Gradually add the powdered sugar, one cup at a time, beating well after each addition.

Step 10

Add the heavy cream and beat until the frosting is light and fluffy.

Step 11

Chop the Reese's Peanut Butter Cups into small pieces.

Step 12

Once the cakes are cooled, place one layer on a serving plate. Spread a generous amount of frosting over the top, then sprinkle half of the chopped Reese's on top.

Step 13

Place the second cake layer on top and frost the top and sides of the entire cake with the remaining frosting.

Step 14

Decorate the top of the cake with the remaining chopped Reese's and mini Reese's candies. Drizzle chocolate syrup over the top for an extra indulgent touch, if desired.

Step 15

Refrigerate the cake for at least 30 minutes to set the frosting. Bring to room temperature before serving.
